Strings and Unified Field Theory

TL;DR

This paper argues that string theory inherently predicts a unified field theory where all objects are geometrical, linking matter fields to geometric structures, and providing a different perspective from traditional general relativity.

Contribution

It presents a novel interpretation of string theory as a unified field theory, connecting matter fields with geometric entities like the metric and non-metricity.

Findings

String theory predicts a unified geometric framework.

The Kalb-Ramond field is identified with the asymmetric part of the metric.

The dilaton relates to non-metricity.

Abstract

It is argued that string theory predicts unified field theory rather than general relativity coupled to matter fields. In unified field theory all the objects are geometrical, for strings the Kalb-Ramond matter field is identical to the asymmetric part of the metric except that the fields contribute to different sides of the field equations. The dilaton is related to the object of non-metricity.
